Quote:
“Nitrogen can be offered in two ways, as nitrate or ammonium. The plant has a strong preference for ammonium. However, with excessive ammonium application, the pH can drop too much, which can result in dieback damage to the roots. This directly leads to loss of yield.”

What do you learn?

▪ To read an analysis and understand how a fertigation scheme is calculated
▪ How the plant absorbs nutritional elements
▪ What are main and trace elements, and what function they have
▪ How to recognise a deficiency
▪ Why pH is so important and how to influence it

Results

After this training you:
▪ Know how to read an analysis
▪ Understand how a fertigation scheme is calculated from a recipe into A and B tank filling
▪ Understand how the plant absorbs water and nutritional elements
▪ Know what main and trace elements are and their function
▪ Can recognise a deficiency
▪ Can explain the relevance of pH and EC, why pH is important, and how to influence them
▪ Will understand the principles of fertigation, helping you develop your work in horticulture
▪ Will receive a certificate of participation after the training

How does it work?

This training is delivered online by a senior teacher. Participants are expected to take an active role—joining discussions, answering questions, and completing some homework such as calculations from recipe to A & B tanks.

This training is comparable to a real class, not just a webinar.Planning 2026
